It's nothing bad, no, just need to watch the focus. For example, for parents with more than one child, are you going to do this with all the children, or only your first born until you run out of time when baby 2, 3 and more come along...?
And do you need to focus on other important things if your mate is working 3 jobs, for example, just to make ends meet while you spend extra time teaching that when you could be helping your mate with income?
Just things to think about. Lots more, of course...
